kubectl-cloudflow

Cloudflow plugin for kubectl

Requirements

NOTE ! For this program to work as a kubectl plugin you need to have kubectl 1.13 installed

Kubectl can be found here: https://kubernetes.io/docs/tasks/tools/install-kubectl/

Development Environment Setup

Install go

NOTE ! You will require at least go 1.10+. Check your version with go version.

Fedora:

sudo dnf install golang

Ubuntu:

Install from the binary at: https://golang.org/dl/ and follow the install instructions: https://golang.org/doc/install

(Latest is v1.10.1 as of this writing)

OSX:

brew install golang (latest known/tested version: 1.14)

Set up your workspace and $GOPATH

• Decide on where you want to locate your Golang "workspace", which will also be your $GOPATH
  • For the sake of this example, let's assume you choose $HOME/Development/src/cloudflow/go)
  • Create that directory
  • Now add the following two exports to your bash/zsh config
  • export GOPATH=$HOME/Development/src/cloudflow/go
  • export PATH=$PATH:$(go env GOPATH)/bin
  • Source that config file and verify that the output of go env GOPATH matches what you have just set.

Checkout the CLI

The CLI must be cloned in any directory outside the $GOPATH, this change came about when we switched from dep to go mod.

Build

Build the project

go build

Install the binary in your $(GOPATH)/bin directory

go install

Once the binary is in your $(GOPATH)/bin directory then you should be able to use it with kubectl cloudflow as long as the bin directory is on your $PATH.

Generating documentation

kubectl cloudflow documentation generate -f md -p /user-guide/cli-reference

Release to Bintray

These steps will create a new named release on bintray under cloudflow-tools with convention RELEASE.BUILD-HASH (i.e. 1.0.1.86-687f811).

1. Setup your bintray credentials in ~/.lightbend/cloudflow. Ex)

   realm = Bintray
   host = dl.bintray.com
   user = mybintrayusername
   password = mybintraytoken
   

2. Checkout master branch.

3. Call make release RELEASE_VERSION. Ex)

   $ make release 1.0.1
   ./build-and-release.sh 1.0.1
   Release tag specified: 1.0.1
   Branch not specified. Detected: master
